API calling

Custom API service class:

using System.IO;using System.Net; 

  

using System.Text; 

  

using Microsoft.WindowsAzure.Storage; 

  

using Microsoft.WindowsAzure.Storage.File; 

  

using Microsoft.IdentityModel.Clients.ActiveDirectory; 

  

using System.Threading.Tasks; 

  

final class Dax_ApiMultipleHeaders 

  

{     

  

public static void main(Args _args)    

  

{         

  

   str url = "https://xkcd.com/info.0.json",responsejson;          

  

  WebException    exception;         

  

System.Net.HttpWebRequest   webrequest;         

  

CLRObject          webResponse =null;         

  

System.Exception      ex;

System.Net.WebHeaderCollection   httpHeader;         

  

str      response1;         

  

str       byteStr;         

  

System.Byte[]        byteArray;         

  

System.IO.Stream     stream,Datastream;

System.Text.Encoding             utf8;         

  

ApiTable                        apiTable;         

  

//webrequest = System.Net.WebRequest::Create("URL") as System.Net.HttpWebRequest;

try         

  

{             

  

  new InteropPermission(InteropKind::ClrInterop).assert();             

  

  httpHeader  = new System.Net.WebHeaderCollection();             

  

webResponse = Sys  tem.Net.WebRequest::Create(url);             

  

webrequest = webResponse;             

  

webrequest.set_keepalive(true);             

  

webrequest.set_ContentType("application/json");             

  

webrequest.set_method("get");             

  

webrequest.set_Headers(httpHeader);             

  

webResponse = webrequest.GetResponse();             

  

Datastream = webResponse.getResponseStream();             

  

streamReader = new System.IO.StreamReader(Datastream);             

  

responsejson = streamReader.ReadToEnd();             

  

info(responsejson);               

  

DAx_JsonDataContract object = formjsonserializer::deserializeObject(ClassNum(DAx_JsonDataContract),responsejson);             

  

//List  listData = new List(Types::Class);             

  

//listData = object.parmData();             

  

//ListEnumerator listEnumerator = listData.getEnumerator();               

  

// DAx_JsonDataContract jsonDataContract = listEnumerator.current();             

  

apiTable.Month      = object.parmMonth();             

  

apiTable.Year       = object.parmYear();             

  

apiTable.Day        = object.parmday();             

  

apiTable.Number     = object.parmNumber();             

  

apiTable.SafeTitle  = object.parmsafeTitle();             

  

apiTable.insert();                      

  

}         

  

catch(Exception::CLRError)         

  

{             

  

   ex = CLRInterop::getLastException().getBaseException();             

  

  error(ex.get_Message());             

  

  streamReader.Close();             

  

  Datastream.Close();             

  

webResponse.close();         

  

}         

  

  

  

}   

  

} 

 

Key Points: We need to create contract class which are presenting in API URL those are parameters.
